基于桥墩防护的铁塔基础成品防护技术及其装置设计

为了降低铁塔基础的破损率,提高工程创优质量,根据对基础破损现状的调查、五种基础成品防护方法的对比分析、借鉴桥墩防护技术,提出了基础成品防护技术建议。从保护装置组装方式、接口设置、基础保护范围、保护装置材质四个方面论证分析,提出了保护装置的最佳设计方案。研究结果表明:不采取基础成品防护措施时,基础破损率平均达到7.3%;保护装置的最佳设计方案为楔形组装方式,四边设置接口,对基础四角及棱边、四角纵向延长均采取保护,采用NBR+PVC合成材料,在结构上由固定部件和可调整部件构成。经现场使用验证保护效果明显,还具有防盗、安装拆卸简便、便于运输、循环利用率高等特点。

Protection Technology and Protection Device Design of Tower Foundation Product Based on Bridge Protection

In order to reduce the foundation damage rate, and to improve the quality of engineering, some suggestions on the product protection of foundation are put forward, based on the investigation of damage status of foundation and the comparative analysis of five protection methods of foundation, and reference to pier protection technology. The best design scheme of the protection device is put forward from analysis of assembly mode, interface settings, protection range and material. The results show that the foundation damage rate is achieved 7.3% on average, when the foundation product protection measures are not taken. The best design of protect ion device is wedge assembly, four interface sett ings, protecting four angles, their longitudinal extension and edges, NBR+PVC synthetic materials, the structure composed of the fixed part and the adjusted part. Through the field application, the protection effect is obvious, and it has the characteristics of anti-theft, easy installation and disassembly, easy transportation and high recycling efficiency.
